IntroductionThe objective of this study was to estimate and to characterize the actual patterns of triptan use and overuse in France using a drug reimbursement database.MethodsWe included all people covered by the French General Health Insurance System (GHIS) from the Provence-Alpes-Côte-d'Azur (PACA) and Corsica administrative areas who had at least one dispensed dose of triptans between May 2010 and December 2011. All dispensed doses of triptans, migraine prophylactic treatment and psychotropic medications were extracted from the GHIS database. Triptan overuse was defined as triptan use >20 defined daily doses (DDD) per month on a regular basis for more than three consecutive months. Risk of overuse was assessed using logistic regression adjusted for gender and age.ResultsWe included 99,540 patients who had at least one prescription of a triptan over the 20 months of the study. Among them, 2243 patients (2.3%) were identified as overusers and received 20.2% of the total DDD prescribed. Twelve percent of overusers and 6.9% of non-overusers were aged more than 65 years (OR: 1.81). Overusers did not have a greater number of prescribers and pharmacists than non-overusers. They were more frequently prescribed a prophylactic medication for migraine treatment (56.8% vs 35.9%, OR: 2.36), benzodiazepines (69.9% vs 54.7%, OR: 1.93) and antidepressants (49.4% vs 30.2%, OR: 2.33).ConclusionsThis work suggests that triptan overuse may be due to insufficient prescriber awareness of appropriate prescribing. The off-label prescription of triptans among the elderly necessitates investigating their cardiovascular risk profile in this sub-group.© International Headache Society 2015.
